Wow, I didn't know Philip May was a "trillionaire"! This is too hung up on current events so try a generalisation...
Actually they won't get it... because any region with sentient people will also form at least one cross-traditional-party alliance and preferably multiple alliances, and they will offer their votes to form a government on a competitive basis too. Yes, it's horsetrading but that's how things work anyway, just not on such an above board and refined basis. It's pretty much were Labour's devolution is already tugging us, though like much coming out of the left the implications weren't properly considered (Umm... SNP!). It also has parallels in much of Europe. National party orientated FPTP hasn't exactly worked swimmingly for the NE over the last century has it, and there are huge problems with all forms of PR.
